  1. Remember me? I'm the guy who originated this discussion - LOL. I am delighted that my query has generated so much fantastic and exceptionally intelligent dialogue. I admit that much of what has been said is over my head in terms of technical understanding, but has been enlightening nonetheless. Please keep it going. To me it provides some insight into the complexities of capturing, recording, and producing a digitized version of music and why it has taken so long to have finally arrived at an era where digital recordings actually sound great. This discussion may also parallel ongoing controversy about the best methods for recording and playback surrounding PCM and DSD, and more recently, MQA. I found Bluesman's analogy to movies easy to grasp and very helpful. Thank you sir. But so far, I don't feel like my original question has been answered - at least to my benefit. As best as I can determine, bit depth captures both musical data and dynamic range - it is not exclusively one or the other. Part of my remaining confusion can be attributed to my conception of dynamic range. My simplistic view is that dynamic range is the range of loudness from the noise floor (zero) to the loudest peak in terms of spl.
  2. Thanks for the knowledgeable reply, but it leaves me confused on a couple of levels. It seems like you are saying that bit depth is not relevant to capturing all the musical information needed for a good sounding recording. If so, then why bother going beyond 16 bits? Maybe some of my confusion goes back to computer programming where a 16 bit word can contain only half the data of a 32 bit word. As far as tape hiss is concerned, some of the best sounding recordings I've heard are full of tape hiss, but my ears ignore it, and only notice it when there is no music. The best sounding music has always come when listening to a reel-to-reel tape.
  3. I thought after all this time I was correctly explaining bit depth and sample rates to my non-audiophile friends, but now I"m not so sure. I thought that bit depth or bit size determines how much information can be captured in a single sample taken from an analog signal. So if, for example, you are recording a symphony orchestra, there are lots of instruments creating a lot of complex tonal information and sound levels. This creates a complex analog waveform, and when you take a sample of this waveform, you are going to digitize it and store it in a file. This single sample of the waveform would obviously contain a lot of information about what was happening in this symphony orchestra in that instant of time. The larger the bit depth, the more information you can capture, and you have a better quality file to produce a better quality recording. But now I'm hearing that bit depth is all about dynamic range. That seems too simplistic to me. Any experts out there who can set me straight?
  4. thanks for the suggestion - looks like an excellent affordable option. I kind of put my a/d enthusiasm on hold for a bit after I installed the latest firmware on my DirectStream dac. It sounds so analog now I can't tear myself away.
  5. I'm looking for a good quality but not too pricey A/D converter to transfer my favorite lp's to high qulaity digital flac or aif files. I recently tried the inexpensive Behringer UFO202 with free open recording software Audacity, but was not at all satisfied with the 24/96 results. I'm not sure if the shortcomings are due to the Audacity or the a/d converter inside the Behringer. One mistake I probably made was using the Behringer phonostage rather than the output from my much better Vincent PHO-8 phonostage. Any recommendations on A/D converters or recording software would be greatly appreciated. I've looked into DAW Digital Audio Workstations, but they seem to be overloaded with functions and features I don't need.
  6. The USB Regen provided a marvelous improvement to my Oppo Sonica dac. Then the ISO Regen and LPS-1 increased the sonic benefits by the same degree over the USB Regen. Since then, I was able to move into a PS Audio DirectStream. To my ears, I was no longer able to hear the easily noticeable improvements from the ISO Regen and LPS-1. But knowing how effective Uptone's products have been in the past, and how terrific Uptone treats its customers, I will not hesitate to give the new Ether a try.
  7. Very excited to learn how it does... Can you describe how it would benefit a PS Audio Direct Stream Dac streaming music via its ethernet port? I'd be surprised but thrilled to find it's possible to hear sonic benefits from this device.
  8. I did some additional testing after reviewing your helpful reply. Your comments reinforced my thinking that I might not have set JRiver correctly, so I went back into JRiver DLNA server settings. Changing the output mode from “Original” to “Specified output format only when necessary”, which allowed me to access the DSP studio and set the DSP output settings to match what I had for the USB input. And Eureka! both USB and Bridge II sound so much alike that I can’t hear a difference, and the both sound fantastic! SPL output levels for both were also now equal. Now it looks like I may not need my ISO Regen and LPS-1. Anyone interested? But maybe I should wait for Uptone's new EtherRegen. Thanks for the help!
  9. I am surprised that I am getting decidedly better sound quality from the USB input on my DS dac. I have hundreds of hour of burn-in with music and burn-in tones from Track 8 of the Chesky Test and Burn-in CD using both the USB and Bridge inputs. I am using Uptone Audio’s USB ISO Regen and Ultracap LPS-1 galvanic isolation power supply, which has greatly improved the performance of USB. At worst I would have expected the Bridge II to sound equally good, but it is clearly not to my ears. Less bass, thinner, harsher high frequencies. The Bridge II volume setting needs to be lowered to 94 to equal to spl of the USB input. I am running JRiver MC 24, so all variables may not be the same because JRiver requires use of DLNA to play to the Bridge II, while the USB connection is direct. Is anyone else getting the same results, or the opposite?
  10. Thank you for your response Alex, but I'm still unsure of my path going forward. I've been reading all the positive comments about the LPS-1.2 and the improvements it provides over the LPS-1, and I was ready to place my order for an LPS 1.2, but then you muddied the waters for me with the your EtherREGEN announcement. You seem to indicate that it is not possible to predict whether the EtherREGEN will provide better sound quality in my situation. I don't plan on using Roon or other streaming service, and all my music is sourced from an external hd on my laptop running JRiver, and feeding my DirecStream Jr from an ISO REGEN with LPS-1 I think the music sounds exceptionally good this way. Alex or John, could you make a general recommendation for those of us using USB with the ISO Regen and LPS-1. Should we upgrade to the LPS-1.2 or supercede it with an EtherREGEN if our dacs have both capabilities? Of course that puts you in the position of discouraging the sale of one Uptone product in favor of another. Sorry for that.
  11. Yes, the PS Audio DirectStream Jr has an ethenet/LAN input to its built-in network bridge. The network bridge also has an hdmi input for i2s, which supposedly is superior because it separates the clock from the audio signal. I don't no why, but PS recommends against using wireless ethernet. I'm dubious that sound quality using ethernet to the bridge would improve what I'm already getting from USB with the IR and LPS-1 (or LPS-1.2). If ethernet to a bridge is the superior approach, then I'm hesitant to get the LPS 1.2.
  12. Thank you K and John and tboooe for the help. I'm glad to know a pathway exists to use the future switch. It just occurred to me: Would the ethernet switch supercede the use of a usb for input into the dac? If so, would my IR and LPS-1 then be obsolete to me?
  13. I hope discussion of this topic hasn't stopped yet, because I have a question that may not have been covered. Is this upcoming switch going to be wireless? Is this a dumb rookie question? I'm asking because my audio system is not on the same floor as my modem and router. My PS Audio DSJ has a network bridge that has ethernet and i2s input. The only way to use ethernet would be from a wireless bridge. Would I need to have my cable company run a second cable to my audio room?
  14. Thank you, TAPATRICK, for your feedback. It's re-assuring to know that others share the same or similar impressions. I've only had the DSJ for 2 weeks, and it seems to still be breaking in and getting better, and it does have the latest firmware, which is another reason I am very pleased to own the DSJ with upgradeable FPGA vs pre-programmed DAC chips - good as they may be. I had strongly considered getting the Yggdrasil, but based on others telling me they prefer the DirectStream or DirectStream Junior, I made the plunge for DSJ, although they don't compare price-wise. I am thinking the DSJ is so satisfying because it converts everything do 1 bid dsd? I might be posting the wrong subject matter here. Sorry. If Superdad is watching (like Santa), I wonder if he has any opinion of i2s vs USB using the ISO-Regen.
